Antitrust Multi-District LitigationWon dismissal with prejudice in 51 separate nationwide class actions, which were combined into one MDL proceeding in the Northern District of Georgia. Plaintiffs alleged that defendants conspired to set fuel surcharge levels on “Less Than Truckload” shipments. On behalf of our Fortune 50 client, we obtained a stay of discovery, and moved to dismiss the complaint on the ground that plaintiffs had not alleged facts to establish a conspiracy under the standards set forth by the Supreme Court in Twombly v.
